Paper Abstract

Rapid calculation methods for both transient temperature fields and steady-state temperature fields of laser heat treatments and their theoretic relation are discussed, with application examples of simulating calculation. The applicable conditions of rapid calculation methods for temperature fields are also investigated. The obtained results show that steady-state temperature fields are the ultimate solution of transient temperature fields, in which the time of laser interaction with matter is infinite, and the rapid calculation of transient temperature fields can describe heat interaction of a real laser much better. A quantitative criterion of the rapid calculation methods is given in the application research.
